Working from the 372 build, I did the following:

1. apply activemq.zip to create version 1.1
2. Migrated to 1.1.
2. apply camel.zip to create 1.2 (un-knowingly created it on the root container)
3. tried to migrate from 1.1 to 1.2. The console said the migration was in progress and may take a moment. Of course it never worked but I had no indication of my mistake.

Is there anyway to make this a bit more user friendly, i.e. a message appear that you can't migrate directly to a different patch without rolling back first? Or should it actually let you do this?
